Caching system for chrome devtools protocol

Act as an external cache for chrome

example

import Devtools from "@u4/chrome-remote-interface";
import ChromeRemoteCache from "./ChromeRemoteCache";
import CacheManagerRedisTTL from "./CacheManager";

const delay = (ms: number) => new Promise((r) => setTimeout(r, ms));

async function testAll() {

    remoteCache.cache('www.google.com/maps/dir///');
    remoteCache.cache('www.google.com/maps/vt/');
    remoteCache.cache('www.google.com/images/');
    remoteCache.cache('www.google.com/js/');
    remoteCache.cache('www.google.com/maps/preview/pwa/manifest');
    // www.gstatic.com, maps.gstatic.com, fonts.gstatic.com   
    remoteCache.cache('*.gstatic.com');
    remoteCache.cache('fonts.googleapis.com');
